Hi,
I'm currently looking at a gaming PC and I cannot find a clear way to compare these 2 video cards,
in details I'm evaluating these 2 systems (in order to get a fair/good gaming experience):

Asus N76VZ-V2G-T1131
Core™ i7-3630QM, velocità clock: 2,3 GHz
Chipset: Intel HM76
8192 MB DDR3-1600/PC3-12800
8192 MB DDR3-1600/PC3-12800
LCD 17,3'' 1920x1080 LED 16:9
Hard Disk: 2x 750 GB Sata 7200 rpm
Audio Bang & Olufsen ICEpowe
Scheda Video: Nvidia GeForce GT650M, 2048MB (gddr5)
BLU-RAY WRITER S-MULTI DL
prize:1250 euros

HP - Envy 17-2090el
Cpu intel 2630QM@2Ghz
Chipset Intel HM55
Ram 8GB@1.333 MHz
LCD 17,3 " LED Full HD (1920x1080
DVD+-RW WRITER DL
1x500 GB 7200rpm
AMD Radeon HD 6850M 1GB gddr5
prize: 980 euros

My doubt is not about cpu or memory specs, they looks fine for gaming (am I right?), my doubt is about the video cards.
I have heard that there is huge difference between 6850gddr3 and 6850gddr5 and notebook check has results which are related only to the ddr3 version.
My question is
Has anyone here similar configs? Can you post 3dmark and heaven benchmarks for these graphic cards, 6850m and 650m, at stock speeds ?
What is the best video card (and taking in account the prize gap)?

1200 euros are near my planned limit :) I'm trying to understand if the gaming performance gap worth 270 euros more

Thanks in advance to anyone, for any suggestion (overall impressions on the other hardware components are welcome :) )
Regards
Fabiano

P.s: This is my first post, is this the right subforum for this question?
